Technique.
Background technology
Substantial amounts of drilling wastes can be generated in Process of Oil Well Drilling.Drilling wastes are a kind of extremely complex disperse
System, the waste water and landwaste that are mainly generated by well drilling waste mud, drilling well etc. forms, and has oils, solid suspension, a huge sum of money
It is big to belong to ion concentration height, water-cut variation, it is difficult to which the features such as being dehydrated is the main pollution of generation during current oil exploration
Object.Poisonous and harmful element content is higher in drilling wastes, if directly discharge can cause environment larger harm.Wherein, endanger
The main chemical compositions of environment have hydro carbons, salt, all kinds of polymer, heavy metal ion, the sundries in barite and pitch etc. to change
Property object.These pollutants have the characteristics such as high chroma, high petroleum-type, high COD, high suspended matter, high salinity.At present, very much
In the drilling process in oil field, can near well head excavate a larger mud sump, drilling wastes with drilling process into
Row and generate, and be directly discharged into mud sump, the leakage of discarded slurry and excessive underground water and Soil Surrounding can be caused seriously
Pollution, makes soil lie waste.
Drilling mud and drilling waste water are fluid state, and water-cut variation is larger, are a kind of relatively stable colloid bodies
System.And although well drilling detritus moisture content is relatively low, is not easy to transport and clears up since surface attachment has more mud.At present, state
It inside not yet develops more suitable drilling wastes and collects processing equipment and technique, most of oil field is all using at curing mode
Drilling wastes are managed, i.e., drilling wastes concentration is discharged into mud sump, adds in a large amount of curing agent thereto, are run through chemical anti-
It should realize that dehydrating and curing forms a kind of solid matter of similar soil and emergency burial.And due to curing agent chemical property itself
Limitation, harmful components in drilling wastes after curing still can slow release into soil and groundwater, cause secondary dirt
Dye.In addition, the hardener dose required by such method is larger (account for discarded object total amount 1/3), so as to considerably increase place
Manage cost.
It is more next to drilling wastes emission request in Process of Oil Well Drilling with the continuous reinforcement of China environmental protection dynamics
It is stringenter, it is desirable that in drilling process processing is not landed to the realization of drilling mud discarded object, while strengthen seepage control measure, it is stringent to control
Pollution of the drilling wastes processed to drilling well surrounding enviroment.It therefore, will necessarily be by a manner that curing agent handles drilling wastes
